The Importance of Glaciers
You may not think of glaciers very often. After all, to the average person, they are little more than giant chunks of ice floating around somewhere far away. And in a sense, those who think this are correct. A glacier is fundamentally nothing more than the accumulation of snow compacted over thousands of years to become solid ice. The ice’s density allows the glaciers to float slowly, creating massive rivers of ice that can, over centuries, carve and reshape entire landscapes. Yet, they do much more than float around and break down rocks. Their role in Earth’s delicate environment is much more significant than one might initially consider.
